USES
|
|
Buna-N
|
-35℃~100℃
Short time
-40℃~125℃
|
Also known as nitrile rubber,buna-N has good tensile strength and resistance to abrasion.It is also red\sistant to hydrocarbon products.It is a good general-service material for use in water, vacuum, acid,sails, alkaines, fats, oils, greases, hydraulic oils and ethylene glycol.Buna-N is not recommended for acetone,ketones and nitrated or chlorinated hydrocarbons.
|
|
EPDM
|
-40℃~135℃
Short time
-50℃~150℃
|
Also known as EPT or Nordel, EPDM is a good, general-service synthetic rubber for use in hot-water systems and those containing ketones, alcohol hposphate sters and glycol. EPDM is not recommended for hydrocarbonbased oils, minterals or solvents.
|
|
Chioroprene
Rubber
|
-35℃~100℃
Short time
-40℃~125℃
|
Chloroprene Rubber is recommended for moderate acids, oils, fats, greases and solvents, excellent corrosion resistance.
|
|
VITON
|
-20℃~180℃
|
Fluorine rubber is a fiuorinated hydrocarbon elastomer with excellent resistance to mose hydrocarbon oils and gases and other petroleum-based products. Viton is notrecommendedfor steam service, hot water over 180℃ or concentrated alkalines.
|
|
Silicon rubber
|
-70℃~200℃
|
Silicone Rubber has good resistance to high temperature and low temperature and its chemical is stable. It is recommended for foods, strong acids and weak alkalis
